In total eclipse of a star, New Horizons' future flyby target makes its presence known

Emily Lakdawalla • July 19, 2017

The team reported two weeks ago that the first attempts at observing 2014 MU69 were unsuccessful. But in their third try, on July 17, astronomers in Argentina saw the telltale sign of MU69's presence: a stellar wink.

DPS/EPSC update on New Horizons at the Pluto system and beyond

Emily Lakdawalla • October 25, 2016

Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.

DPS/EPSC update: 2007 OR10 has a moon!

Emily Lakdawalla • October 19, 2016

The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.

Pluto is not the end

One year after the New Horizons Pluto flyby, Emily reflects on its significance.

"Planet Nine" update: Possible resonances beyond the Kuiper belt?

Emily Lakdawalla • March 08, 2016

A new paper by Renu Malhotra proposes that an undiscovered distant planet could have organized extremely distant Kuiper belt objects into orbital resonances.

30th anniversary images of Uranian moons

Emily Lakdawalla • February 02, 2016

January 24 was the 30th anniversary of the Voyager flyby of Uranus. Uranian moons have been on my mind ever since New Horizons sent us close-up images of Charon. On the occasion of the anniversary, Ted Stryk produced latest-and-greatest versions of the Voyager views of these worlds.

Randall Munroe is a genius at disguising seriously educational infographics as funny jokes.

Theoretical evidence for an undiscovered super-Earth at the edge of our solar system

Emily Lakdawalla • January 20, 2016

It's looking likelier that there is an undiscovered planet orbiting beyond the Kuiper belt. If it's there, it's roughly 10 times the mass of Earth (or about half the mass of Neptune), likely never gets closer to the Sun than about 100 AU, and takes more than 10,000 years to orbit the Sun.

Pluto updates from AGU and DPS: Pretty pictures from a confusing world

Emily Lakdawalla • December 21, 2015

Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.

Charon in 3D

Emily Lakdawalla • October 13, 2015

Last week, the pile of New Horizons LORRI camera raw image releases included nine frames from a high-resolution mosaic on Charon. Together with the color MVIC view, they make a 3D global photo of Pluto's moon. Other recently released goodies include a global backlit color image of Pluto and the first image that resolves the tiny moon Styx.

New Horizons releases new color pictures of Charon, high-resolution lookback photo of Pluto

Emily Lakdawalla • October 02, 2015

Now that New Horizons is regularly sending back data, the mission is settling into a routine of releasing a set of captioned images on Thursdays, followed by raw LORRI images on Friday. The Thursday releases give us the opportunity to see lovely color data from the spacecraft's Ralph MVIC instrument. This week, the newly available color data set covered Charon.

Spectacular New Horizons photo of Pluto's hazes and mountains: How it was made

Emily Lakdawalla • September 17, 2015

Today, New Horizons released a stunning new image of Pluto's backlit mountains and hazes. I explain how the image was taken with its Ralph Multispectral Visible Imaging Camera.

Roundup of the September 11, 2015 New Horizons raw image release

Last Friday the Internet received its first post-encounter pile of goodies from the New Horizons flyby of the Pluto system.

Pretty Pictures: Downlink of the Full New Horizons Data Set Has Begun

Emily Lakdawalla • September 10, 2015

New Horizons has begun the long process of downlinking all the images it acquired during its July Pluto flyby.

New Horizons extended mission target selected

Emily Lakdawalla and Casey Dreier • September 01, 2015

The New Horizons mission has formally selected its next target after Pluto: a tiny, dim, frozen world currently named 2014 MU69. The spacecraft will perform a series of four rocket firings in October and November to angle its trajectory to pass close by 2014 MU69 in early January 2019. In so doing, New Horizons will become the first flyby craft to pass by a target that was not discovered before the spacecraft launched.

Three space fan visualizations of New Horizons' Pluto-Charon flyby

Emily Lakdawalla • August 25, 2015

It has been a difficult wait for new New Horizons images, but the wait is almost over; Alan Stern announced at today's Outer Planets Advisory Group meeting that image downlink will resume September 5. In the meantime, a few space fans are making the most of the small amount of data that has been returned to date.

Looking back at Pluto

Emily Lakdawalla • July 24, 2015

I don't think anyone was prepared for the beauty -- or the instant scientific discoveries -- in this "lookback" image of Pluto, captured by New Horizons shortly after it flew by.

Latest New Horizons picture of Charon: oddly familiar

Emily Lakdawalla • July 16, 2015

The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.
